It may not display well but I'm posting an image of the second part of the Pi activity I posted the other day. This kept the group engaged for over a period. It may not help them to understand the deep meaning of pi or its relation to a circle but they definitely got a sense of the decimal representation of pi and struggled with some of the birthdates, since a simple Google search will not suffice. Do they now appreciate pi more? How will I assess the learning from this? I hope you will see that this was more than just meaningless busywork to keep them quiet! See if you can find all of the mathematicians in less than 10 minutes!
